If you haven't resolved this yet I suggest installing the legacy TWAIN/WIA scan driver available on the downloads page for your machine. A direct link to that file is below. You'll want to re-enable 'remote start TWAIN' before setting it up. I have yet to try the newer 'scan experience' app but I have used the older one many times with much success.

Thank you for using the Support Forum.I see no one has responded to this post yet. So, at this point I would recommend contacting your local Xerox Support Department to speak with a Product Specialist for more assistance. Please call 1-800-821-2797 or 1-800-835-6100
The scanning function works scanning to SMB, but I am trying to get it to scan from an application on Windows (PDF-XChange), but I'm finding that I'm unable to get it to work. When I try to start a scan from PDF-XChange, it churns for a while and throws an error "pxvlib: scanning process failed" - the printer does not respond at all to the request. I've tried the Xerox Print and Scan Experience app and it initiates the scanning process on the printer, but after the imager finishes its run, the software thows an error "Unable to connect to the device. Check the connection and try again." The scan jobs sit in the Active Jobs list as Processing until I delete them.
The printer is network connected, Remote Start (TWAIN) is enabled (though the behaviour was the same with it disabled), I've updated my drivers, but to no avail. Does anyone have any ideas?
